  • Patent number: 10320116
    Abstract: A terminal unit includes inner conductors (35) fixed to front ends of wires (38). A dielectric (10) has a holding member (11) and a cover (27) united in a direction intersecting an axial direction of the wires (38) and accommodates the inner conductors (35). Guide recesses (17) are formed on the holding member (11) and extend in a front-rear direction. Guide ribs (33) are formed on the cover (27) and can slide in contact with the guide recesses (17) to allow relative displacement of the holding member (11) and the cover (27) in the front-rear direction while keeping the holding member (11) and the cover (27) united. Guides (19) bring the holding member (11) and the cover (27) closer together in a uniting direction while displacing the cover (27) from a temporary assembled position to a proper assembled position in the front-rear direction.
